Physical Volume States
A volume is in the inventory if an entry (in the inventory) for the volser is in the
database. The following states are associated with a physical volume:
Inaccessible
A volume is in the library manager inventory,but is currently in a location
that is not accessible by the cartridge accessor.
Misplaced
A volume is in the inventory,and the library manager determines that it is
not in the position indicated by the inventory.
Mounted
A volume is currently mounted on a drive or a mount was accepted for the
volume.
Unreadable
The vision system read the external bar-code label on a volume that has a
defect in the external label or the volume does not have an external label.
This state is not modified if the vision system is not operational.
Manual mode
The volume required movement when the 3494 was in Manual mode. The
volume is flagged in the inventory as a Manual mode volume until it is
successfully moved or audited in Auto mode or during inventory update.
Logical Volume States
A volume is in the inventory if an entry (in the inventory) for the volser is in the
database. The following state is associated with a logical volume:
Mounted
A volume is currently mounted on a drive or a mount was accepted for the
volume.
Physical Volser Validity Checking
As a physical cartridge is added to the tape library inventory, the library manager
checks the volser to ensure that it is readable, is not already in the inventory, and is
not otherwise invalid.
The Convenience Input⁄Output Station will be in either Import Mode or Insert Mode,
depending upon the capabilities of the VTSs in the library and the configuration of
the library.
The Convenience Input⁄Output Station is in Insert Mode when the library does not
have a VTS that is capable of Import/Export operations.
The Convenience Input⁄Output Station is in Import Mode when the library has at
least one VTS that is capable of Import/Export operations.
The mode of the Convenience Input⁄Output Station is stored so that the Library
Manager “remembers” the mode across shutdowns. Once the mode is determined,
the stored mode is used each time the Library Manager initializes. The mode will
change if the configuration changes or the VTS capabilities change.
